Título: | Critical Role of Electrical Resistivity in Magnetoionics |

A series of highly nanocrystalline cobalt nitride (Co-N) thin films (85 nm thick) with a broad range of electrical properties exhibit markedly different magnetoionic behaviors. Semiconducting, near stoichiometric CoN films show the best performance, better than their metallic and insulating counterparts. Resistivity reflects the interplay between atomic bonding, carrier localization, and structural defects, and in turn determines the strength and distribution of applied electric fields inside the actuated films. This fact, generally overlooked, reveals that resistivity can be used to quickly evaluate the potential of a system to exhibit optimal magnetoionic effects, while also opening interesting challenges. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevApplied.16.034042 | URI: | http://hdl.handle.net/10261/260553 | DOI: | 10.1103/PhysRevApplied.16.034042 | Identificadores: | doi: 10.1103/PhysRevApplied.16.034042 e-issn: 2331-7019 |
